AI personalities

This article is considered accurate for the current version (2.3) of the game.

AI empires act and behave based on their AI Personality type which in turn is dictated by factors like what ethics, traits and government type the empire has. The personality type will direct the empires' behavior in terms of foreign- and domestic policy, fleet budgeting, political behavior and general empire characteristics. The empire's personality can be found in the diplomacy screen, just under the ethics list.

Weapon preference - Preferred weapon type the empire will use on its ships.

Hull ratio - Amount of hull boosters the empire will have on its ships.

Armor ratio - Amount of armor the empire will have on its ships.

Shields ratio - Amount of shields the empire will have on its ships.

The above ratios determine what percentage Hull/Armor/Shield attachments the empire's ship designs will have. As an example, an empire with 0.5x Shield ratio and 0.5x Armor ratio will use ship designs where the Utility slots will contain Defense components consisting of 50% Shields and 50% Armor.

Honorbound Warriors value honor and martial prowess above all other things. They will seek out worthy foes to fight and have little respect for weaklings and pacifists.

If the process of assigning an AI personality to an empire fails (usually due to a glitch) and the AI empire in question is left without an assigned personality when the game begins, the game will assign it the Despicable Neutrals personality as a fallback. Otherwise, this personality type should not appear in a normal playthrough.
